All-welded steel ball valves 11s31p with a standard bore (made with a narrowed bore) are used on pipelines as a shut-off device that completely blocks flow of the working medium. Connecting pipes of the valve allow it to be welded directly to the pipeline, reducing the cost of installation work. Installation position of the valve on the pipeline is any. The valve should be installed on the pipeline in places accessible for inspection and maintenance.
Features of the 11s31p ball valve:
- All-welded body ensures high reliability and no leaks.
- Compact construction length simplifies installation on pipelines.
- Tightness class “A” according to GOST 54808 guarantees a complete absence of leaks.
